"*donk* The Graphics card in the system is not supported"
That suggests to me that it's detecting another graphics card to the one you say you have. Does your mother board have an onboard chipset that isnt as disabled as it should be ?
Or have you perhaps still got the old card listed in the device manager as disabled even with it removed, get device manager to show you hidden devices and make sure only your 6800 is the only grpahics card shown.
Might be something daft like that ;)
